摘要：

Efficient laser emission at 1.06 mu m was obtained from a diode-laser quasi-continuous wave pumped Nd0.04Gd0.86Lu0.10Ca4O(BO3)(3) (Nd:GdLuCOB) single crystal. An uncoated, 6.0-mm long, ZX-cut Nd:GdLuCOB medium yielded laser pulses with 1.76 W peak power for absorbed pump pulses of 5.49 W peak power, corresponding to an overall optical-to-optical efficiency eta(oa) = 0.32; the slope efficiency was eta(sa) = 0.44. Comparison is made with an uncoated XY-cut Nd:GdCOB medium (4.0-at.% Nd doping and 6.8-mm length) from which laser pulses with 1.74W peak power (at optical efficiency eta(oa) = 0.25) and 0.31 slope efficiency were obtained. The improvements in laser emission of Nd:GdLuCOB at the fundamental wavelength are important for future self-frequency doubling in ZX principal plane of this crystal. (C) 2015 Elsevier B.V.
